ExcAvAT'INc-MACH IN srncirrcArIoN forming pm of Letters retest Ne. 580,505, dated April `1 e, 1897.

Application lled June 27, 1896.

To aZZ whom, t may'wncern: n Be it known that We, JOSEPH L. POTTER and 4 HARRY G. HAWEKOTTE, citizens of the United States, residing atlndianapolisjn the county 5 of j Marion and State of Indiana, have invented certain newand useful Improvements in Excavating-Machines; and We do declare .the following tobe a full, clear, and exact de#` scription of the invention, such as will en- Io able others skilledin the art to which it appertains to make and use` the same, reference being had to the accompanying drawings', and tothe letters of reference marked thereon,

- which form a part of this speciiication. y r5 Our invention relates toan`improvement lin a machine for raising shovels or scoops filled with dirt from the bottom of a trench,

.to the surface and to cause said scoops to be zo t' further provide means to transport the scoops from one end of the trench to the other.

Thescoop is raised by means of ropes or cales, one end of whichv is connected to the supply the power. to

hoisting-engine drums, and the other ends` drums onthe shafts.'

are connected-to the i The scoop will descend bygravity to the bottom of the trench.`v

n Our invention has for its object to provide a simple and inexpensive means for the ex-l 3o cavation Vand elevation. of materials and to Y transport same back and forth on the line of ,the track. .1. f f. p

- With this end in view our inventionconf sists in certain -features of construction and combination of parts, which will be hereinafter fully describedand pointed out in the In excavating for trenches, sewers, andthe like, where the material'is to' be raised to the 4eV surface and to be transferred longitudinally for dumping, this de` vice, which is the subject of thepresent int. .vention, is of great convenience, as it aiords 1 'a safe, cheap,'practical, and readily .cQn-i It has been the custom to first loosen the dirt by means of picks Aand shovels and lling the y receptacle'on the varioustrench-machines and then elevate it to the surface,l but our ...p-5o invention fills the scoop automatically by iilled with dirt, .and

serial No. 5975.31." N0 modem means of the cables, carriages, and engines by simply manipulating the drum-levers which are attached to the engine.

Referring to thedrawings, Figure l is a side elevation of our device. Fig. 2 is a part plan 5 5 view; and Fig. 3 isa sectional end View onthe` lineZZ,Fig. j

` In the drawings, A is a superstructure which is'mounted on the Wheels A and travels on the track B. On top of this superstructure the carriage D is mounted andhas the wheel C traveling on the track C. On the top of the carriage D are mounted the Iriain' drums M and M' having supplemental drums 'on each sidefm and m', respectively. These drums are mounted on the shafts Ky and K'.

Hand H' are the ratchet-wheels, and E, E', E, and E3 are the dogs or finger-pawls.

P represents one end of theNhoisting-engine frame, provided with the drums T and R,

which have the operating-handles X and Y, respectively, and are connected to suitable friction clutches to revolve the drums in either direction. Said drums are lloose on -the shaft and only revolve when said frictionlevers are engaged therewith. `The two drum- `shafts of the engine are geared together and are engaged by a third, or a series of intermediate gears to the gear on the main shaft of the engine. i y

t is the long rope or cable and is attached to the drum T of the engine and vpasses up and over the pulley S,.then over the pulley S'- lengthwise across the carriage and overthe pulley S2, then downward' and around the pulley S", which is attached to the superstructure, then upward and attached "co the The rope or cable ,fr is securedto the drum R of the engine, then passes upward and overI the wide pulley W and over the wide pulley W', and is then attached to the main pulley M. The ropes or cables 'r andjTare swung around thelarge pulleys M and M', respectively, in `opposite directions. 95 Q and O' are ropes or cables which are secured to thebrackets e. and a, respectively.

`,Said brackets are vattached'to the scoop G. A

The opposite end of these ropes is attached tothe supplemental drums mand'm',respec roo tively. The scoop G is preferably made to about the contour shown and has the sides d dand the back and bottom g,

` two main pulleys or The dotted lines representing the scoop in Fig. 1 show the scoop in the act oi' filling with dirt or other material from an embankment.

lIn operation to lower the scoop release the dogs or pawls E, E', E2, and E3, discngage the frictional clutch-levers X and Y, andthe scoop will fall by gravity to the bottom of the ditch. Then engage the lever Y, which will cause the front of the scoop to incline upward and at the saine time will convey the carriage toward the left and cause the scoop to gouge into the embankment, thus filling the scoop. rl`hen engage both levers X and Y and hoist the scoop to the surface. Now lengage the pawls or dogs, and by simply manipulating the levers X and Y the carriage will transfer the material either to the right or left longitudinally. In-duxnping the dirt at the end of the ditch lsimply release the dogs E and E', which will cause the front of the scoop to fall downward, thus relieving the scoop of its contents.

Having thus described our invention, what we claim, and desire to secure by Letters Pat ent of the United States, is

1. In an excavating and conveying machine, the combination with a movable trestle and the carriage movably mounted thereon; of. drums mounted on the shafts of said carriage, supplemental sheaves or drums on each side of said main drums, the scoop-and the ropes connecting the same to the supplemental drums and the ropes secured to the main drums for either advancing said frame or lifting said scoop, substantially as shown and described.

2. In combination, the movable trestle, the movable carriage mounted thereon, the shafts journaled on said frame, the main and supplemental drums `carried by said shafts, the cable or ropes connected to saidvsppplenlental drums, the'scoop connected by said ropes to said supplemental drums, and the ropes or cables leading from the engine-'drums and passing over pulleys carried by said frame and around the pulleys carried by said trestle and connected to the main drums, the winding of said ropes on said engine-drums being adapted to either raise said scoops or advance said carriage, substantially as shown and de'- scribed.

3. In an excavating and conveying machine,

' the combination with the xnevable trestle and carriage; of the mai'iid'runis journaled te said 'l carriage; the ,small `or supplemental drums on each side of said )nain drums; the ropes or cables tooperate said main drums; the ropes attached to said supplemental drums;

'the scoop swung upon'said supplemental and .the

ropes between each pair of drums,

ratchet wheels and pawls for locking said drums, substantially as shown and described. In testimony whereof we ax our signatnresinp,esenceefAwe-witnesses:
